Exploitation of customers

So one mudflap for my Navara costs R550 at the Nissan dealership. Go figure. A piece of rubber? To put that in context..... A universal SET of four mud flaps for the whole vehicle costs R100. That's R25 for one. That means that Nissan asks near 2000% more. So do you still want to buy a Nissan?.....do you?.....really?......
